I made gel air fresheners last night The colour didn't turn out very nice but they smell lovely. I made 2 as the sachets of gelatin set 1 pint of liquid.I used lavender essential oil plus red and blue food colouring with a tablespoon of salt & just under a pint of water (it's the first time I've used gelatin for anything and wanted to make sure I didn't make it too runny!)

They're good for up to 4 weeks,apparently after that you might get mould growth although I've read you can add vodka to the mix to combat that but vodka isn't something I have around the house.
